Hegner Reactor Systems Branch Complete Me have reviewed Florida Power and Light Company's response to TflI Action Item II.K.3.25, as transmitted to RSB by DL for the Turkey Point Nuclear Power Stations.
This Action Item requires licensees to demonstrate that the integrity of their reactor coolant pump (RCP) seals is maintained (e.g.,
adequately cooled) during a loss-of-offsite-power event.
The applicant's response stated that the reactor coolant pump sea'Is are cooled by two independent methods:
(1) the chemical and volume control
- system, and {2) the component cooling water system.
During a loss-of-off-site-power event, the RCP motor is de-energized and both cooling systems to the seals are terminated.
However, the diesel generators are automatically started and "either" the seal injection flow or the component cooling water to the thermal barrier heat exchanger is automatically restored within seconds.
Either of these cooling supplies is adequate to provide seal cool-ing and prevent seal failure during a loss-of-offsite-power event.
Me find the licensee's submittal acceptable, conditional upon the clarifica-tion of which system is automatically restored during a loss-of-offsite-power event (e.g..
component cooling water, seal injection, or both).
He request that you keep us appraised as to the applicant's response.
Should you have questions regarding our review, please contact Jack Guttmann at X29442.

This Action tern requires licensee to demonstrate that the integrity of their reactor oolant pump (RCP) ea'Is is maintained (e.g.,

The applicant's response stated tha the re tor coolant pump seals are cooled by two independent methods:
) th chemical and volume control
- system, and (2) the component cooling r system.
During a loss-of>>off-site-power event, the RCP motor is de-rgized and both cooling systems to the seals are terminated.
- However, e d sel generators are automatically started and "either" the seal inde ion flo or the component cooling water to the thermal barrier heat exch ger is auto atically restored within seconds.
Either of these-cooli g suppl ies is
/equate to provide seal cool-ing and prevent. seal'ailure ring a loss-of-of'ite-power event.
Me find. the licensee's su ittal acceptable, condit nal upon the clar ifica-tion of which system is tomatically restored during loss-of-offsite-power event (e.g.,
